The invention relates to a method of automatic gain control in a base station of a cellular radio network and to a network part in a cellular radio network. In response to the request, the operating system determines whether one or more potential errors in execution of one or more processes other than the first process executing on the first core would be caused by disabling the predetermined task on the first core. T-shaped recesses may also be located within a single diffusor. The electroactive organic layer and the metal layer are formed sequentially on the conductive substrate or the conductive layer, wherein the electroactive organic layer comprises metal atoms and serves as a seed layer, resulting in the metal layer formed in-situ. A lower power consumption and less sensitivity to disturbing fields are further advantages.
